Predictions by social identity theory (SIT) and relative deprivation theory (RDT) concerning preferences for strategies to cope with a negative in-group status position were tested. The focus of the present research was a comparison of the theories regarding their differential patterns of prediction. For this purpose, a natural sample within a specific historical situation was investigated: East Germans after the German unification. First, the predictive power of SIT and RDT variables was tested separately. In a second step, a possible integration of the theories was addressed. Combining the SIT variables and RDT variables led to an integrated model indicating a differential pattern of prediction for intergroup strategies. The RDT components explained the collective responses, whereas SIT constructs were related to individual strategies.  相似文献

一、语言,符号系统作为符号系统的语言,就其结构而言可区分为两个不同的平面:表达平面和内容平面.因此整个符号系统的特点就是两个方面的统一:即人们区分的能指(signifiant或signans)和所指(signifi?或signatum)的统一.能指和所指对应于语言的表达和内容这两个平面.语言符号的能指和所指之间的关系是由这些符号的内容和表达之间的关系所决定的.内容平面上的符号和表达平面上的符号之间的关系,是索绪尔原理(即关于语言  相似文献

A short proper name retrieval test was found to discriminate between unselected subjects and age- and education- matched patients affected by Alzheimer's type dementia at a stage where the Mini-Mental State Examination could not detect a difference between these groups. The proper name retrieval task also compared favorably with the 3MS, a more sensitive, modified version of the MMSE. These findings suggest that proper name retrieval could be used to an advantage and become a routine component of short batteries for the early detection of Alzheimer's disease.  相似文献

The general incidence of Savant Syndrome was assessed in Finland. First, a survey was made of all 583 facilities which served people with mental retardation. Second, letters asking for information regarding people with Savant Syndrome were published in two key Finnish journals of the field. We received reports of 45 cases of Savant Syndrome. This makes an incidence rate of 1.4 per 1,000 people with mental retardation. The most common form of exceptional skills was calendar calculation, followed by feats of memory.  相似文献

The aim of the paper was to further explore the complementarity of the working memory models postulated by Pascual-Leone and Baddeley. Five-, six-, eight-, and nine-year-old children were assessed on two working memory tasks that have frequently been used within the respective streams of research: the Mr. Peanut task and the Corsi blocks task. Results indicated a developmental increase in spatial short-term memory for both tasks. Concurrent spatial suppression reduced performance on the two tasks in all four age groups. By contrast, articulatory suppression interfered with recall only on the Mr. Peanut task, and in only the older children. The two models were shown to make their own specific contribution to the interpretation of the data, attesting to their complementarity. Pascual-Leone's theory offered a clear explanation of the results concerning the central aspects of working memory, that is, the stepwise age-related increase in performance, whereas Baddeley's model provided a convincing account of the findings regarding the peripheral phonological and visuo-spatial components, that is, the effects of articulatory and spatial suppression.  相似文献

This study describes differences in course and outcome, defined by GSI (SCL-90) at admission, discharge, and one‐year follow‐up, in 458 patients receiving in‐patient treatment for long‐standing symptom and/or personality disorders.
A K-mean cluster analysis identified seven subgroups of patients, representing four clinical distinct, meaningful patterns of change: early improvement, late improvement, relapsing after discharge, and a severe chronic course.
Main findings: the subgroups had unique correlates among socio-demographic, diagnostic, and treatment-related characteristics. One of the relapsing groups had a high rate of Cluster C personality disorders, whereas the other had low participation in the anxiety programme. The group with severe chronic course showed occupational maladjustment and high number of both Axis I and II disorders.
Implications: anxiety patients should participate in anxiety-treatment programmes, Cluster C patients should be followed and monitored for relapse, and severe chronic patients should be offered specialised treatment for their co‐existing substance abuse and/or eating disorders.  相似文献

The study evaluated the off-line relationship of attention, memory and other cognitive performances with the auditory event-related potentials P3 (P300) and N2. The sample comprised 200 middle-aged construction workers. Verbal, visuomotor and memory tests were administered. Attentional domains were examined using CogniSpeed software. Slowed reaction times in the test of sustained attention (vigilance) were associated with delayed P3 latency (p < 0.001) and decreased P3 amplitude (p = 0.005), as well as with delayed N2 latency (p < 0.001). Visuomotor slowing in Digit Symbol was also related to delayed P3 latency (p = 0.030) and decreased P3 amplitude (p = 0.014). In contrast, mild cognitive impairment, short- and long-term memory, and concentrating or sharing attention with high working memory demands were not related to P3. The results suggest that P3 is linked to attentional performance with low working memory demands rather than to effortful working memory updating, retrieval from memory stores, or mild cognitive impairment.  相似文献
